Thread the machine before you sew anything
Threading is the first step every time you sew, and it looks more complicated than it is. Start with the presser foot up — this opens the tension discs inside the machine so thread can slide between them. Lower the presser foot only after threading is complete, or the thread will jam.
Follow your machine's threading path exactly as shown in the manual or the diagram printed on the machine itself. Most machines thread from top to bottom: the spool sits on a post at the top, thread goes down through a tension dial (usually a wheel or slot), then through a guide or two, then through the needle. The needle itself has an eye (the hole) that faces a specific direction — check your manual to see whether yours faces front or side.
Insert thread into the needle eye from the correct direction, then pull both thread ends toward the back of the machine and hold them there while you lower the presser foot. This traps the thread and prepares the machine to catch the bobbin thread underneath.
Wind and insert the bobbin
The bobbin is a small spool that holds thread underneath the fabric. Before your first stitch, you need to wind thread onto an empty bobbin. Place an empty bobbin on the bobbin winder (a post on top of the machine), guide thread through the bobbin winder's tension guide, and wrap it around the bobbin a few times by hand. Press the bobbin winder against the machine's wheel or press start if your machine is electric.
The machine will wind thread onto the bobbin automatically. Stop when the bobbin is full — most machines have a sensor that stops automatically, or you can stop manually when the bobbin looks full but not overstuffed. Cut the thread and remove the bobbin.
Insert the wound bobbin into the bobbin case (the small compartment under the needle plate). Drop it in and pull the thread through the tension spring as shown in your manual. Pull the bobbin thread up through the needle plate hole by turning the handwheel toward you while holding the top thread. You should see a loop of bobbin thread come up through the plate. Pull both threads toward the back and hold them while you're ready to sew.
Key Takeaways
- Always raise the presser foot before threading so the tension discs open and thread can pass through them.
- Follow your machine's threading diagram exactly — thread path varies by machine model, and incorrect threading causes skipped stitches and jams.
- Wind the bobbin before you insert it, and pull the bobbin thread up through the needle plate by turning the handwheel toward you.
- Hold both the top thread and bobbin thread toward the back of the machine before you start sewing to prevent the first stitch from puckering.
- Test your tension on scrap fabric first — uneven stitches mean the tension dial needs adjustment, not that you're doing something wrong.
Set your stitch length and width
Most machines have a dial or digital display for stitch length (how far the fabric moves forward with each stitch) and stitch width (how far the needle moves side to side). For a basic straight stitch, set the width to zero — the needle stays in one place side to side. Set the length to 2.5 millimeters, which is a standard medium stitch that works for most cotton fabric.
Shorter stitches (1.5 to 2 mm) are stronger and work well for seams that take stress. Longer stitches (3 to 4 mm) work for quilting or basting (temporary stitching). You can change these settings anytime, even mid-project — just stop with the needle down, adjust the dial, and continue sewing.
Position fabric and lower the presser foot
Place your fabric under the presser foot with the edge you want to sew about one-quarter inch from the needle. The presser foot holds fabric flat against the feed dogs (the metal teeth that move fabric forward). If the presser foot is up, fabric will slide around and your stitches will be crooked.
Lower the presser foot by pushing down the lever on the back of the machine. You should hear or feel a click. Now the machine is ready to sew. Never lower the presser foot with the needle down in the fabric — raise the needle first by turning the handwheel toward you, then lower the foot.
Start sewing with a slow, steady pace
Hold both thread tails loosely toward the back of the machine as you begin. Press the foot pedal slowly — do not press hard or fast on your first tries. The machine's speed depends on how far you press the pedal, not how hard. A light, steady pressure gives you control and lets you see what's happening.
The fabric will feed forward automatically under the presser foot. Your job is to guide it gently, not pull it. Pulling stretches the fabric and can break the needle. Let the feed dogs do the work — they move the fabric the exact distance you set with the stitch length dial.
Sew a few inches on scrap fabric to get the feel of the pedal and the machine's speed. Most beginners press too hard at first. A light touch gives you better control and straighter seams.
Backstitch at the start and end of every seam
A backstitch is a few stitches sewn backward to lock the thread in place so it doesn't unravel. At the start of a seam, sew forward two or three stitches, then press the backstitch button (or lever) and sew backward over those same stitches. Then release the button and sew forward normally.
At the end of the seam, sew forward to the edge of the fabric, then press the backstitch button and sew backward two or three stitches. This locks the thread at both ends. Without backstitching, the first and last stitches will come loose as soon as you pull on the fabric.
Raise the presser foot and remove fabric
When you reach the end of your seam, raise the needle by turning the handwheel toward you until the needle is all the way up. Then raise the presser foot by pushing the lever. The fabric is now free to pull out.
Pull the fabric toward you gently — do not yank. Leave about four inches of thread attached to the fabric. Trim the thread with scissors, leaving a tail long enough that it won't pull back through the fabric. If you trim too close, the last stitch can come loose.
Troubleshoot common first-time problems
If stitches look loose and loopy on top, the top tension is too loose — turn the tension dial to a higher number. If the bottom looks loopy, the bobbin tension is too tight or the bobbin thread is not threaded correctly through the tension spring. Check the bobbin first before adjusting bobbin tension, which is harder to reach.
If the needle breaks, you probably hit the fabric with the needle or the needle was inserted backward. Raise the presser foot, raise the needle all the way up, and remove the broken needle. Insert a new needle in the correct direction (check your manual), then re-thread the machine from scratch.
If the machine jams or makes a grinding sound, stop when ready and raise the presser foot. Check that the presser foot was down when you started sewing and that the bobbin is wound and inserted correctly. Rethread the top thread with the presser foot up. Most jams happen because the presser foot was up during threading.
Frequently Asked Questions
Do I need to wind a new bobbin every time I sew?
No. Wind a new bobbin only when the current one runs out of thread. Most bobbins hold enough thread for several seams. Keep a few wound bobbins on hand so you can swap them out quickly instead of winding a new one mid-project.
What's the difference between the presser foot being up and down?
When the presser foot is up, the tension discs are open and thread can pass through them during threading. When it's down, the discs close and hold the thread at the correct tension. The foot also holds fabric flat against the feed dogs so stitches are even. Always raise it before threading and lower it before sewing.
Can I sew backward without the backstitch button?
Some machines don't have a dedicated backstitch button — instead, you reverse the direction lever or press a reverse button. Check your manual to find which control reverses your machine. The result is the same: a few stitches sewn backward to lock the thread.
Why does my thread keep breaking?
Thread breaks most often because the needle is bent or inserted backward, the bobbin is wound too tight, or the presser foot was up during threading. Check the needle first — hold it up to the light and look for a bend. If it's straight, rethread the machine with the presser foot up and make sure the bobbin thread passes through the tension spring.
How tight should I hold the fabric while sewing?
Guide the fabric gently with your fingertips, but don't pull it. The feed dogs move the fabric forward automatically — pulling against them stretches the fabric and can break the needle or cause skipped stitches. Think of your hands as guides, not drivers.
